Never Donate Via SMS

Recently I donated to the Shelter charity via SMS, after doing this I keep on getting phone calls from 02076197597, after doing some research it appears the phone calls are from a company called Listen (www.listenuk.org) and they do this spam phone calling for various well known charities like Unicef and NSPCC, this also means that these charities are wasting donated money employing this company. My advice is never SMS donations to any company as they might just use a spam company like Listen.
